Re: [WIN7] Recommended SSD System Tweaks?

It so happens that I often chat to a senior guy where I work whose job in part involves figuring out the impact of various disk technologies on our product line. And he tells me it does make a difference. Unfortunately his reports aren't public.

Misalignment is mostly a write problem, and more so on a not-new drive. (You can't overwrite an SSD block; the controller needs to allocate an erased block, and schedule the old one for erasure.)

FWIW, not all SSDs are equal. Different controllers choose to optimize for (note rare example of correct usage of the word) different scenarios.

In that situation, I can understand the requirement. But for the 99% of consumers, not so much. Let Windows 7 do its thing and the rest of us should be fine. After several drive failures (OCZ) I have been using Intel SSDs with no problems.

There's no alignment issue with Windows 7 - it knows how to do the alignment.

Previous versions of Windows did not; so those are the systems on which you need to fix the alignment (if you care). That includes the update from not-Win7 to Win7 case, of course.

If in doubt check the alignment, its a few command line commands and you can see if its aligned.

if its not then fix
this applies to all SSD's and all 4k block drives (often called advanced format, as the 4k block size was needed to make drives over 2TB)
